About Drainage Design Management System for Window 4.8.0

The Drainage Design Management System for Windows (DDMSW) program is a pre-processing tool for HEC-1 rainfall-runoff model. This new release of DDMSW provides new features and capabilities that enhance the development of HEC-1 model and use of Rational Method as well as in the post-processing of model results.

In addition to the improvements on the hydrology module, significant refinements have also been implemented on the river mechanics module including:

Lateral Erosion

Launch-Able Riprap

Low-Flow Incisement Methodology

Riprap Sizing

Sediment Yield Analysis

Also, street drainage hydraulics and storm water drainage systems modeling are two features that are currently implemented in this new release of the program.
